44	SubCol does not return the correct columns.	asalafranca	danirus	"When I run this peace of code very strange things happend. 
  Matrix k = ((1,2,3),(1,2,3),(1,2,3));
  Set    s = SetOfReal(4.02,4.03);
  Matrix m = SetCol(s);
  Matrix f = Floor(m);
  Matrix d = m - f;
  Matrix p = RProd(d, 100);
  Set   s2 = MatSet(p);
  Set   s3 = BinGroup(""<<"", s2);
  Matrix r = SubCol(k,s3);
  WriteLn (""Set  s2 = \n""<<s2);
  WriteLn (""Matrix r = \n""<<r);
  Matrix r2 = SubCol(k, SetOfReal(2, 3));
  WriteLn (""Matrix r2 = \n""<<r2);
If I ask about any of the auxliary variables Tol answers correctly, but it has 
problems with the SubCol function. It sometimes throws  
""

"", and  gives out the wrong columns. Try changing the initial values in the ""Set s"", 
it is a lot of fun."	defect	closed	high		Math	head	major	fixed
